HMAP
This web server was fingerprinted as: Apache/2.0.4O-2.2.3 (Unix)
which is not consistent with the displayed banner: Apache/2.0.55 (Ubuntu) PHP/5.1.6

If you think that Nessus was wrong, please send this signature
to www-signatures@nessus.org :

Try to provide as much information as you can: software & operating
system release, sub-version, patch numbers, and specific configuration
options, if any.

Nessus ID : 11919
HTTP Server type and version
The remote web server type is :

Apache/2.0.55 (Ubuntu) PHP/5.1.6


Solution : You can set the directive 'ServerTokens Prod' to limit
the information emanating from the server in its response headers.

Nessus ID : 10107
HTTP TRACE Method Enabled

Synopsis :

Debugging functions are enabled on the remote HTTP server.

Description :

The remote webserver supports the TRACE and/or TRACK methods. TRACE and TRACK
are HTTP methods which are used to debug web server connections.

It has been shown that servers supporting this method are subject to
cross-site-scripting attacks, dubbed XST for "Cross-Site-Tracing", when
used in conjunction with various weaknesses in browsers.

An attacker may use this flaw to trick your legitimate web users to give
him their credentials.

Solution :

Disable these methods.

Port domain (53/udp)
DNS Cache Snooping

Synopsis :

Remote DNS server is vulnerable to Cache Snooping attacks.

Description :

The remote DNS server answers to queries for third party domains which do
not have the recursion bit set.

This may allow a remote attacker to determine which domains have recently
been resolved via this name server, and therefore which hosts have been
recently visited.

For instance, if an attacker was interested in whether your company utilizes
the online services of a particular financial institution, they would
be able to use this attack to build a statistical model regarding
company usage of aforementioned financial institution. Of course,
the attack can also be used to find B2B partners, web-surfing patterns,
external mail servers, and more...

For a much more detailed discussion of the potential risks of allowing
DNS cache information to be queried anonymously, please see:

Risk factor : Low

Nessus ID : 11002
Usable remote name server

Synopsis :

The remote name server allows recursive queries to be performed
by the host running nessusd.


Description :

It is possible to query the remote name server for third party names.

If this is your internal nameserver, then forget this warning.

If you are probing a remote nameserver, then it allows anyone
to use it to resolve third parties names (such as www.nessus.org).
This allows hackers to do cache poisoning attacks against this
nameserver.

If the host allows these recursive queries via UDP,
then the host can be used to 'bounce' Denial of Service attacks
against another network or system.

See also :

http://www.cert.org/advisories/CA-1997-22.html

Solution :

Restrict recursive queries to the hosts that should
use this nameserver (such as those of the LAN connected to it).

If you are using bind 8, you can do this by using the instruction
'allow-recursion' in the 'options' section of your named.conf

If you are using bind 9, you can define a grouping of internal addresses
using the 'acl' command

Then, within the options block, you can explicitly state:
'allow-recursion { hosts_defined_in_acl }'

For more info on Bind 9 administration (to include recursion), see:
http://www.nominum.com/content/documents/bind9arm.pdf

If you are using another name server, consult its documentation.

Risk factor :

Medium / CVSS Base Score : 4

Risk factor : Low

Nessus ID : 11002
Version of BIND

Synopsis :

It is possible to obtain the version number of the remote DNS server.

Description :

The remote host is running BIND, an open-source DNS server. It is possible
to extract the version number of the remote installation by sending
a special DNS request for the text 'version.bind' in the domain 'chaos'.

Solution :

It is possible to hide the version number of bind by using the 'version'
directive in the 'options' section in named.conf

Risk factor :

None

Plugin output:

The version of the remote BIND server is : 9.3.2
